Dictyotaceae
Dictyotaceae is large family of brown algae. Members of this order generally prefer warmer waters than other brown algae. One genus in this order is calcareous, Padina, the only calcareous member of this class. Lobophora variegata often presents a beautiful blue iridescence due to microscopic bacteria which live on the surface of the blades. A number of genera are known as forkweed (e.g. Dictyota, Glosophora, Dilophus, Dictyopteris, Pachydictyon and Lobospira.
